The reproductive center of Beijing General 3A Hospital provides IVF and oocyte cryopreservation services. Some of the more than 400 hospitals with IVF qualification approved by the Health Planning Commission can also provide cryopreservation services for oocytes. The cost varies from hospital to hospital, about 2~3W. Freezing eggs in Chinese mainland is very troublesome. Infertile couples who want to cryopreserve oocytes must have three certificates, namely, ID card, marriage certificate and birth certificate. In Chinese mainland, young single women can't go to oocyte cryopreservation. So many women choose to go to Hongkong or oocyte cryopreservation, Taiwan Province Province. Many customers we receive here are from the mainland. I hope the answer can help you!
